    Steve, thanks for the reply and info. The latest cumulative update solved the problem. It downloaded as usual and did the install. This time it actually installed and there was no installation error. I don't know if Microsoft knew of this problem or I got lucky. Everything is now updated and working fine. This is a surface pro i7 withTera drive.

    Thanks again 😊

    Yep, I think it was .Net 3.5 as well... I found this fix somewhere on the web I just documented more clearly for others to implement since it took me over two weeks to correct my system, and I keep a clean system...

    Hi,

    I had the same problem. I first deactivated Malwarebytes but this did not resolve the problem. I then turned off .Net 3.5 and restarted my device. Then installed the 2002-07 Cumulative update KB 5015814 for Windows 11 via Check for updates and IT WORKED !! It took longer to download and install than usual but IT WORKED. I then reactivated .NET 3.5 and Malwarebytes.

    For me it sounds it was a problem with .Net 3.5 since deactivating Malwarebytes only did not do the job.

    I hope it helps others.
